The present invention relates to improvements in pipe supports, more particularly to such as are employed to secure the clownspouts of eaves troughs to the Walls of build ings. The invention is, of course, capable of other applications and may be employed as a support for pipes and tubes generally, whether vertical, horizontal or inclined.

For supporting down-spouts on the walls of buildings, usually metal straps are employed, the said straps embracing the pipe orspout and being fastened to the walls of the building by nails. Unless these straps are very carefully made and mounted with great care by skilled mechanics upon the building walls, they mar the appearance of the building. Even when close attention is given to the manufacture and mounting of the same, these straps impair the apperance of the building to a great extentbecause they are plain straps, lacking ornamentation of any kind.

The inain objects of the present invention are to provide a casing-like construction for housin the stra s above referred to and to b 7 so construct the same that they are adjust able to fit varylng slzes of pipes or tubes and also to take care of thevariatmns in the distance at which the pipes or tubes are offset from the adjacent wall.

Another object of the invention is to provide a pipe support casing which simple in construction, eflicient in operation and capable of manufacture on a commercial scale, or in other words one which is not so diflicult to produce as to be beyond the reasonable cost of such a contrivance.

lVith these and other objects in View, which will more fully appear as the nature of the invention is better understood, the same consists in the combination, arrangement and construction of parts hereinafter described, pointed out in the appended claims and illustrated in the accompanying drawings, it being understood that many changes may be support casing, constructed in accordance with the present invention; Fig. 2is a top plan view thereof; Fig. 3 is a section taken on line 33 of Fig. 1; Fig. f is an elevationof a portion of a blank, on a larger scale, of which one element of the casing is produced; Fig. 5 is an elevation of a portion of the element formed of the blank shown in Fig. l; Fig. 6 is a side elevation of the detail shown in F 5 Fig. 7 is a section similar to the one shown in Fig. 3, on a larger scale, of the joint between two elements of the casing;.and Fig. 8 is a side elevation of the detail shown in Fig. 7.

The pipe support casing is made of sheet netal and comprises three sections, denoted in the drawings by the numerals 10, l1 and 12. The central section. 10 is substantially U-shaped, as clearly appears from Figs. 2

and 3 of the drawings, to fit around the down spout, and is provided all around its upper and lower edges with inwardly turned flanges 13, the free edges 14: of which are adapted to abut against the dowri-spout of the eaves trough, so that the spout embracing portion of the pipe support is encased or housed by the section 10. The sections 11 and 12 are alike in construction, each of the same being joined, in a manner hereinafter to be described, with one of the ends of the section 10. The sectionslO and 11 maybe of any suitable configuration, each of the same be ing provided with inwardly turned flanges 15, so as to fit over and encase those portions of the pipe support which are attached to the walls of the building.

Adjacentthe ends of the U-shaped section 10 and in proximity of and parallel to its flanges 13 the said section is provided with slits 16, and between these slits the end portions of the section 10 are vertically corrugated, as shown at 17. Each corrugated portion terminates in a tab 18, bent at right angles to the corrugated portion and extending into the adjacent section 11 or 12, as the case may be, of the device. The corrugations are provided in the U-shaped section 10 to make the latter contractible and extensible so as to take care of the variations of the oli'setting of the down spout from the adjacent wall.

The sections 11 and 12 of the device are each formed from a blank 19, shown in Fig. 4 of the drawings. This blank is provided adjacent its inner end with a transverse slit 20, wedge-shaped in the longitudinal center line of the blank, as shown at 21. In forming the section, the blank is bent along the slit back upon itself, as shown in Fig. 5, whereby that portion of the blank which is bounded by the wedge-shaped portion of the slit is bent outwards, as shown in Fig. 5, to form a projection 21". The blank is then bent along the longitudinal marginal dotted lines 22 to form the flanges 15. The free edge of that portion of the blank which has been bent back upon the body portion thereof is then bent inwards, as shown at 23 in Fig. 5 of the drawings.

In assembling the device, the tabs 18 of the section 10 areextended through the slits 20 into the sections 11 and 12. The free ends of the'tabs, denoted by the numerals 24, are then bent around the inwardly projecting portions 23 of the sections 11 and 12, and the triangular projections 21 of the sections 11 and 12 are bent against the innermost corrugations 17 of the sections 11 and 12. In this manner a casing-like structure is formed, in which the pipe support is housed when the said casing-lil re structure is applied around the support. In order to hold the device upon thebuilding wall, nails are driven at the triangular cut-off portions 25 through the sections of the device into the building wall, each nail penetrating one of the outer sections of the device and the adjacent tab of the central U-shaped section thereof.

What I claim is 1. A pipe support casing comprising a central U-shaped section provided with inwardly bent flanges along its longitudinal edges,

each end portion of said U-shaped section being provided in parallel relation to and close to said flanges with longitudinal slots and the end portions between said slots being transversely corrugated to permit of contraction and expansion, a tab formed upon each corrugated portion, said tabs extending at rightangles to said corrugated portions, two end sections fitted to said tabs, each end section extending at right angles to the adjacent corrugated portion of said U-shaped section and being provided with inwardly extending flanges for spacing the body portion thereof from the adjacent building wall, each end sec tion having a transverse slit at its inner end and the body portion of each end section being bent back upon itself along said slit, said tabs being inserted into said slits and their outer ends being bent inwardly against the free edges of said bent back portions of said outer sections, and a projection on each end section bent against the adjacent innermost corrugation of said U-shaped section.

2. A pipe support casing comprising a central U-shaped section provided with inwardly bent flanges along its longitudinal edges, a tab formed upon each end portion of said U-shaped section, said tabs extending at right angles to the end portions of said U-shaped section, two end sections fitted to said tabs, each end section extending at right angles to the adjacent end portion of said U-shaped section and being provided with inwardly extending flanges for spacing the body portion thereof from the adjacent building wall, each end section having a transverse slit at its inner end and the body portion of each end section being bent back upon itself along said slit, said tabs being inserted into said slits, and a projection on each end section bent against the adjacent end portion of said U-shaped section.

3. A pipe support comprising a central U-shaped section provided with inwardly bent flanges along its longitudinal edges, a tab formed upon each end portion of said U-shaped section, said tabs extending at right angles to the end portions of said U-shaped section, two end sections fitted to said tabs, each end section extending at right angles to the adjacent end portion of said U-shaped section and being provided with inwardly extending flanges for spacing the body portion thereof from the adjacent building wall, and means for preventing withdrawing of said tabs from said end sections the end portions of said central section adjacent said tabs being transversely corrugated to permit of contraction and expansion.

4. A sheet-metal casing for co-operation with a pipe support having a U-shaped por tion fitting over the pipe and end portions for attachment to the building wall, comprising a central U-shaped section provided with inwardly bent flanges along its longitudinal edges for enclosing that portion of the pipe support which is fitted over the pipe, a tab formed upon each end portion of said U-shaped sect-ion, said tabs extending at right angles to the end portions of said U-shaped section, two end sections fitted to said tabs, each endsection extending at right angles to the adjacent end portion of said U-shaped section and being provided with inwardly extending flanges for housing those portions of the pipe support which are attached to the building wall, and coacting means on said U-shaped section and said end sections wholly disposed within the inwardly bent flanges of said end sections for preventing withdrawing of said tabs from said end sections inde pendently of means which secure said casing to the wall.
